In the Beginning

According to this model, the observable universe developed approximately 13.8 billion years ago from an extremely hot and dense early state. The Big Bang was not an explosion of matter from one point into preexisting empty space. Instead, space itself expanded while the universe cooled and its matter and radiation evolved.

Major evidence for the Big Bang model includes the continuing expansion of the universe, the observed abundance of light elements, and the cosmic microwave background radiation.

The Singularity and the Limits of Physics

When Einstein’s equations are extended backward in time, they approach an initial boundary commonly called the Big Bang singularity.

The singularity theorems developed by physicists Roger Penrose and Stephen Hawking showed that, under certain physical conditions, general relativity predicts that the universe’s past cannot be extended indefinitely.

However, a singularity does not necessarily describe a physical point that science has directly observed. It may instead indicate that general relativity has reached the limit of its usefulness. Scientists do not yet possess a complete, experimentally confirmed theory of quantum gravity capable of describing the universe’s earliest instant.

Genesis does not present equations or identify a physical mechanism for the origin of space, time, matter, or light. Its theological declaration is that creation exists because God commanded it. The words “In the beginning” identify creation as having an origin, while “Let there be light” presents light as dependent upon the will of the Creator.

Light Before the Sun

In modern physics, light is a form of electromagnetic radiation. The early universe contained intense radiation long before the Sun existed.

During the universe’s earliest stages, photons repeatedly interacted with free electrons, making the universe hot and opaque. Approximately 380,000 years after the Big Bang, the universe cooled enough for electrons and atomic nuclei to combine. Photons could then travel more freely through space.

That ancient radiation is now detected as the cosmic microwave background, commonly called the CMB. It is the oldest electromagnetic light that scientists can directly observe.

The CMB was predicted by physicists Ralph Alpher and Robert Herman, accidentally discovered in 1965 by Arno Penzias and Robert Wilson, and later measured with increasing precision by the COBE, WMAP, and Planck space missions.

The first stars formed much later, and the Sun did not form until approximately 4.6 billion years ago. Modern cosmology therefore recognizes that electromagnetic radiation existed long before the Sun.

The Penrose Low-Entropy Problem

The early universe also presents what physicists call the low-entropy problem. Although the universe was extremely hot, its gravitational field was remarkably smooth and ordered.

Small variations in density, later measured in the cosmic microwave background, eventually developed through gravity into stars, galaxies, and clusters of galaxies.

Mathematical physicist Sir Roger Penrose argued that the early universe occupied an extraordinarily special gravitational state. Using phase-space and black-hole entropy considerations, Penrose estimated the required precision as approximately:

In simple terms, the early universe was not merely energetic. It began in a highly constrained state of gravitational order.

Scientists continue to debate whether this order should be explained through a deeper physical law, cosmic inflation, a multiverse, a quantum boundary condition, or a theory that has not yet been discovered.

Quantum Cosmology and the No-Boundary Proposal

Quantum cosmology attempts to apply quantum mechanics to the universe as a whole.

In 1983, physicists James Hartle and Stephen Hawking introduced the Hartle–Hawking no-boundary proposal. Their model suggests that, near the universe’s earliest state, ordinary time may have behaved more like a spatial dimension.

Under this proposal, the universe would not necessarily begin at a sharp temporal edge or with a single instantaneous starting spark. Instead, ordinary time may have emerged gradually from an earlier quantum state.

The Hartle–Hawking proposal remains a theoretical hypothesis rather than an established description of the universe’s origin.

Other proposed models include Alexander Vilenkin’s quantum-tunneling proposal, loop quantum cosmology, inflationary models, and bouncing-universe models. These approaches remain subjects of scientific debate.

None of these models demonstrates that the universe emerged from absolute philosophical nothingness. They begin with mathematical laws, quantum states, fields, geometries, or boundary conditions. They attempt to describe how an early universe might behave, but they do not settle why physical reality or its governing laws exist.

Science, Scripture, and the Cinematic Experience

This science component does not claim that Genesis is a modern physics textbook or that current cosmological theories prove the biblical account. Instead, it identifies points at which modern observations are compatible with the Genesis sequence: the universe has an early history, radiation existed before the Sun, and the cosmos began in an exceptionally ordered physical state.

Genesis addresses the ultimate source, authority, and meaning of creation. Cosmology investigates the physical development of the universe. Where science describes expansion, radiation, entropy, and quantum models, Genesis declares that the universe exists because God created and ordered it.

The ocean, mist, hovering movement, and transition from darkness into light in this experience are artistic interpretations. They are not claims that Genesis supplies those physical details.

The cinematic imagery is designed to help viewers meditate on the central theological message of the passage: the universe is not self-existent, and light appears at the command of God.
